SELF-ROLLING BALL 0R GLOBE.

Application filed January 9, 1908.

T 0 all whom it may concern:

Be it known that I, ALBERTO L. DAY, a citizen of the United States, residing at Ivesley, in the county of Washington and State of Maine, have invented certain new and useful Improvements in Self-Rolling Balls or Globes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a self-rolling ball or globe.

The object of the invention is to provide means within a ball or cylinder for propelling it and which is especially adapted for use in a toy.

represents a sectional view of the ball with the operating mechanism shown in elevation. Fig. 2 represents a perspective view of the swinging power supporting frame detached. Fig.3 represents a vertical section taken at right angles to Fig. 1.

In the embodiment illustrated a ball 1 is shown having disposed therein at diametrically opposite points blocks 2 and 3 in which is fixedly mounted a shaft 4 which forms the axis of the ball. Suspended from this shaft 4 is a swinging frame 5 preferably comprising a U-shaped member 5" with its ends connected by vertically spaced cross bars 5 and 5 and loosely mounted on'said shaft 4 preferably near its ends, said member 5 being concentric with the inner face of the ball 1.

An upright 6 is supported centrally within the frame 5 one end being revolubly mounted in a post 7 carried by a shaft 4 and its other end in the frame member 5 A coil spring 8 is secured at one end to the upright 6 and has its other end attached to the frame member 5 and is adapted to be wound by a key (not shown) which engages the end mounted in the member 5 A ratchet wheel 9 is fixed to said upright 6 and is engaged by a pawl 10 mounted on the lower face of a main bevel gear 11. A revoluble shaft 12 arranged parallel with the shaft 4 passes through the post 7 and is mounted in bearings 13 and 14 in the member 5.

Specification of Letters Patent.

In the accompanying drawings,-Figure 1 Patented Sept. 8, 1908.

Serial No. 409,971.

In the use of this device after the spring 8 is wound the power thereof causes the upright or arbor 6 to turn and through the gear 9 and pawl 10 imparts motion to the main gear 1 1 from which motion is imparted to the shaft 12 through the pinion 16 and through the gears 17 and 18 to the shaft 4 which being fixed to the ball 1 causes it to revolve with it.

Pinion 15 runs on loose shaft 12, and the main beveled gear 11 is guided by the same.

I claim as my invention A self rolling ball having a shaft passing through the center thereof and fixed at diametrically opposite points to the inner face of said ball, a post carried by said shaft, a U-shaped swinging member loosely mounted on said shaft and connected at its ends by vertically spaced cross bars, a revoluble upright mounted at one end in said U-shaped member and at its other end in said post, a coiled spring fixed at one end to said upright and at its other end to said U-shaped member, a ratchet on said upright, a beveled gear wheel on said post having a pawl for engagement with said ratchet, a rotary shaft mounted in said U -shaped member and having longitudinally spaced beveled inions for engagement with said gear whee a pinion carried by said rotary shaft, and a pinion fixed to said first mentioned shaft and meshing with the pinion on said rotary shaft.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERTO L. DAY.
